Current MS-based proteomics has facilitated the identification of large numbers of proteins from complex mixtures. The bovine plasma proteome has the potential to provide a wealth of information concerning the biological state of an animal. However, during MS-based experiments, higher abundance proteins such as albumin and immunoglobulin G (IgG) can hinder the identification of potentially important proteins that are present in much lower abundance. While a variety of readily available technologies exist for the depletion of multiple high-abundance proteins from human, mouse and rat samples, there are few available for bovine. In this study, we report the depletion of >97% of albumin and >92% of IgG from bovine plasma.
